Description

The drilling bit grinding make-up machine

Technical field

The utility model relates to the machinery that grinds after a kind of process tool abrasion, and particularly a kind of special use is drilled with the grinding make-up machine of Steel Plate Guide Drill head.

Background technology

General drill bit promptly can produce the abrasion phenomenon in use, when noise vibration taking place in the drilling process, entering and have some setbacks or when getting out situations such as non-circular hole, promptly represent drill bit to wear away excessively or the size of drill bit, angle have departed from original drilling condition, so drill bit need be ground.

The mode of abrasive drill mainly contained two kinds in the past, and a kind of is to adopt manpower to grip drill bit with hand abrasive machine is ground, and another kind is drill bit to be set up on the tool grinding machine grind.

Because manpower grips drill bit to abrasion wheel grinding, need the quite abundant personnel of abrasive drill experience, and need repeatedly to measure drill bit angle and size in the process of lapping, guarantee that drill bit does not have disappearances such as noise vibration, non-circular hole when boring, therefore, quite time-consuming with the manpower abrasive drill, the operation of abrasive drill adopts the tool grinding machine to carry out the grinding of drill bit mostly instead at present.

The utility model content

The technical problems to be solved in the utility model provides a kind of drilling bit grinding make-up machine, and it can finish the drilling bit grinding of suitable cutting angle fast.

For solving the problems of the technologies described above, the utility model adopts following technical scheme:

A kind of drilling bit grinding make-up machine, comprise: pedestal, grinding group, the first feeding group and the second feeding group, described grinding group includes the motor of assembly on pedestal, and the formed grinding wheel that driven by motor, and this formed grinding wheel has the axial grinding face and radially grinds anchor ring;

The described first feeding group is disposed on this pedestal, and the first feeding group comprises first slide for the drill bit assembly, and the direct of travel of this first slide is formed the abradant surface of shape emery wheel towards described grinding;

The described second feeding group is disposed on this pedestal, and the second feeding group comprises second slide for the drill bit assembly, and the direct of travel of this second slide is formed the grinding anchor ring of shape emery wheel towards described grinding.

Owing to adopt technique scheme, drilling bit grinding make-up machine of the present utility model is ground by axial abradant surface of the relative respectively formed grinding wheel with the second feeding group of the first feeding group and grinding anchor ring radially, does not need professional grinding personnel just can finish suitable bit cutting angle fast to grind thereby make.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail.

As shown in Figure 1, 2, drilling bit grinding make-up machine of the present utility model, it includes pedestal 10, grinding group 20, the first feeding group 30 and the second feeding group 40, wherein:

This pedestal 10 provides following member assembly and the energy firm support;

This grinding group 20 includes the motor 21 of assembly on pedestal 10, and the formed grinding wheel 22 that driven by motor 21, and this formed grinding wheel 22 has axial grinding face 221 and radially grinds anchor ring 222;

This first feeding group 30, be disposed on this pedestal 10, the first feeding group 30 includes the slide rail 32 of assembly in first bracing frame 31 of pedestal 10, two assembly in first bracing frame 31, is slidedly arranged on first slide 33 of slide rail 32 and the screw rod 34 that is disposed at first bracing frame 31, and screw rod 34 drives first slide 33; Wherein first slide 33 has one and is nested with hole 331 for drill bits 50 assembly location, and first slide 33 is driven by screw rod 34 and is abradant surfaces 221 of organizing 20 formed grinding wheels 22 towards this grinding along the direct of travel of

slide rail

32, and 31 assembly of first bracing frame have side cut distance measuring device 35 (see figure 3)s in addition;

This second feeding group 40, be disposed on this pedestal 10, this second feeding group 40 includes second bracing frame 41 of assembly in this pedestal, assembly is in the angle adjustment lever 42 of this pedestal 10 and second bracing frame 41, two assembly are in the slide rail 43 of second bracing frame 41 and be slidedly arranged on second slide 44 on the slide rail 43, wherein second slide 44 has one and is nested with hole 441, being nested with hole 441 is for drill bit 50 assembly location, and the direct of travel of second slide 44 is along slide rail 43 and organize the grinding anchor ring 222 of 20 formed grinding wheels 22 towards this grinding, and second bracing frame, 41 superordinates have dust cap 45 in addition.

Shown in Fig. 4,6, at first drill bit 50 terminal installations are positioned at being nested with in the hole 331 of first slide 33, allow drill bit 50 head ends towards grinding group 20, and adjust first position of slide 33 on slide rail 32, after making that drill bit 50 head ends touch side cut distance measuring device 35, shift out side cut distance measuring device 35, and lock first slide 33 appropriate location on slide rail 32, allow drill bit 50 be able to abradant surface 221 rubbings of relative formed grinding wheel 22, simultaneously grinding anchor ring 222 rubbings of the tip 53 relative formed grinding wheels 22 of drill bit;

For grinding at drill bit 50 side cuts 51, can see through fine setting and control screw rod 34, allow first slide 33 move suitable distance towards grinding group 20, can reach the amount of grinding of adjusting drill bit 50 side cuts 51.
